BACKGROUND

In the human receptor tyrosine kinase superfamily, the ERBB familycomprises four members: ERBB1 (epidermal growth factor receptor orEGFR), ERBB2 (HER2), ERBB3 (HER3), and ERBB4 (HER4). The ERBB receptorsshare an overall similar structure with a ligand-binding ectodomain, asingle transmembrane domain, and an intracellular kinase domain, whichis active in ERBB1, HER2 and ERBB4, but defective in ERBB3. A diversearray of ligands has been identified for the ectodomains of ERBB1,ERBB3, and ERBB4, but not HER2. Ligand binding induces conformationalchange in receptors to form homo- and hetero-dimerization. Withoutligand binding, the extracellular domain of HER2 is already fixed in aconformation that resembles the other ligand-activated ERBB members,making it a preferred dimerization partner for other ligand-bound ERBBs.The dimerized receptors activate the intrinsic kinase activity, leadingto phosphorylation of tyrosines at cytoplasmic tails. The ERBB receptorsdiffer in kinase potency, phosphorylation sites, and substratespecificity. The phosphorylated tyrosines serve as the docking sites torecruit downstream effectors and activate multiple cascades ofintracellular signaling pathways, including the anti-apoptotic/survivalPI3K/AKT and the mitogenic RAS/RAF/MEK/ERK pathways. In normal cells,the activity of ERBB receptors is under tight control to regulatevarious cellular processes, such as growth, proliferation, developmentand differentiation, survival and apoptosis, cell shape and adhesion,migration, and angiogenesis. Yarden et al., Nat. Rev. Mol. Cell. Biol.2001, 2, 127-137; Hynes et al., Nat. Rev. Cancer 2005, 5, 341-354.

As a major proliferation and survival engine for cells, constitutiveactivation of ERBB receptors, particularly ERBB1 and HER2, is oncogenicand can be a strong driver for tumorigenesis in cultured cells andanimal models. In addition, the activated receptors accelerate cancerdevelopment by promoting tumor angiogenesis and metastasis. Persistentactivation can result from overexpression of the receptors, productionof excessive ligands, or generation of activating mutations in theectodomains and kinase domains of the receptors. Yarden et al., Nat.Rev. Mol. Cell. Biol. 2001, 2, 127-137. In humans, genetic alterationsin ERBB genes and other genes that lead to similar deregulation of ERBBreceptors are frequently identified in majority of carcinomas, such aslung, breast, colon, prostate, brain, head and neck, oesophagus, ovary,cervix, bladder, stomach, and endometrium cancer. The aberrantactivation of ERBB receptors is in general an adverse prognosticindicator for higher recurrence rate and shorter survival time.Nicholson et al., Eur. J. Cancer 2001, 37, 9-15; Slamon et al., Science1997, 235, 177-182.

Given the compelling association of activation of ERBB receptors withhuman cancers, ERBB1 and HER2 are among the kinase targets for drugdevelopment, aiming to tame signaling transduction pathways for cancertreatment. To reverse the abnormal activity of ERBB receptors in tumors,monoclonal antibodies targeting the extracellular domains of ERBB1 andHER2 and small molecule chemicals inhibiting the intracellular kinasedomains have been developed.

The monoclonal antibody drugs attack the ERBB receptors with highspecificity and attenuate ERBB-mediated signaling by prevention ofligand binding and receptor dimerization, elimination receptors fromcell surface through endocytosis, inhibition of shedding ofextracellular domain, and activation of immune system. Hudis, N. Engl.J. Med. 2007, 357, 39-51. Cetuximab and panitumumab, two anti-ERBB1antibodies, have shown improvement in response rate and the rate ofprogression-free survival in the treatment of metastatic colon cancereither as monotherapy or in combination with chemotherapies. Inaddition, cetuximab has also been approved for the treatment of locallyadvanced, unresectable or metastatic squamous cell carcinoma of the headand neck. Ciardiello et al., N. Engl. J. Med. 2008, 358, 1160-1174.Anti-HER2 antibody trastuzumab binds to the domain IV of the HER2receptor at the juxtamembrane position. In clinical development,trastuzumab has demonstrated increased overall survival rate in early-and metastatic-stage breast cancer patients with tumors showing IHC 3+HER2 overexpression or FISH gene amplification ratio of at least 2.0.Using the same criteria for patient selection, pertuzumab, which bindsto a distinct epitope at the domain II of the HER2 receptor, has beenfound to further increase the complete response rate by addition totrastuzumab and docetaxel regimen as a neoadjuvant treatment forpatients with locally advanced, early-stage breast cancer. Gradishar, NEngl. J. Med. 2012, 366, 176-178.

Development of small-molecule ERBB1 kinase inhibitors (ERBB Hs) hasbecome an evolving paradigm for using cancer genomics to guide targeteddrug development and treatment. Gefinitib and erlotinib, the first twoERBB1I drugs, are reversible ATP mimetic inhibitors that bind to thewild-type ERBB1 catalytic domain to inhibit tyrosine kinase activity. Inunselected patients of non-small cell lung cancer (NSCLC) or pancreaticcancer, only erlotinib has demonstrated clinical benefit by modestlyincreasing overall survival. Ciardiello et al., N. Engl. J. Med. 2008,358, 1160-1174. In a subset of NSCLC patients that harbor activatingmutations within ERBB1 tyrosine kinase domain, both gefitinib anderlotinib treatments are highly sensitive and can achieve lastingefficacy as monotherapy. These drug-responding mutations are mostlyin-frame deletions nested around Leu-Arg-Glu-Ala from position 747 to750 in ERBB1 exon 19, or a leucine to arginine substitution at position858 (L858R) in exon 21.

However, the initial response to erlotinib or gefitinib relapses in10-14 months by developing resistant mutations in tumors. Among them, aT790M gate-keeper point mutation in the exon 20 of ERBB1, which poses asteric interference to drug binding, is found in over 50% of acquiredresistant tumors. To overcome the resistance from T790M mutation andconfer sustained ERBB1 inhibition, the second-generation ERBB Hs havebeen developed, some of them are irreversible ERBB1 and HER2 dualinhibitors. The irreversible compounds overcome the kinase bindinghindrance from T790M mutation by better fitting into the mutated bindingpocket and forming covalent bond with the protein amino acid residues.Additionally, irreversible ERBB Hs appear to cause slower acquiredresistance to the treatment than reversible inhibitors. Sharma et al.,Nat. Rev. Cancer 2007, 7. 169-181.

In preclinical testing, afatinib, a second-generation ERBB1I, inhibitedthe growth of NSCLC HCC827 cells, which harbor the sensitive exon 19deletion, and is 50-fold more potent than erlotinib in inhibition ofgrowth of NSCLC H1975 cells, which has a T790M mutation in-cis with theL858R mutation. However, afatinib also inhibits A431 cells, whose growthis driven by a wild-type ERBB1, 100-fold more potent than H1975. Thedifference in potencies portends that, in cancer patients, the compoundcould inhibit wild-type ERBB1 completely before it reaches sufficientblood level for pharmacological effect on T790M mutant ERBB1. Sincewild-type ERBB1 inhibition has been reported to cause dose-limitingtoxicity in virtually all previously ERBB1I drugs, the preferentialinhibition of wild-type ERBB1 over resistant mutant pose a potentialchallenge for afatinib to achieve high enough dose for T790M mutantinhibition. Consistent with the preclinical discovery, clinicaldevelopment has found afatinib only showed equivalent efficacy toerlotinib or gefitinib in patients with sensitive mutations, but failedto demonstrate statistically meaningful superiority to erlotinib andgefitinib in treating patients with acquired T790M resistant mutationeven at the maximum tolerated dose. Langer, J. Clin. Oncol. 2013, 31,3303-3330. Thus, there is a clear and unmet need to develop effectivetherapeutics for treating a proliferative disease, especiallydrug-resistant cancer.

The compounds provided herein are intended to encompass all possiblestereoisomers, unless a particular stereochemistry is specified. Wherethe compound provided herein contains an alkenyl or alkenylene group,the compound may exist as one or mixture of geometric cis/trans (or Z/E)isomers. Where structural isomers are interconvertible, the compound mayexist as a single tautomer or a mixture of tautomers. This can take theform of proton tautomerism in the compound that contains, for example,an imino, keto, or oxime group; or so-called valence tautomerism in thecompound that contain an aromatic moiety. It follows that a singlecompound may exhibit more than one type of isomerism.

For example, the compound of Formula I , when R^(2A) is hydrogen, mayexist in any of the following tautomeric forms as shown below.

The compounds provided herein may be enantiomerically pure, such as asingle enantiomer or a single diastereomer, or be stereoisomericmixtures, such as a mixture of enantiomers, e.g., a racemic mixture oftwo enantiomers; or a mixture of two or more diastereomers. As such, oneof skill in the art will recognize that administration of a compound inits (R) form is equivalent, for compounds that undergo epimerization invivo, to administration of the compound in its (S) form. Conventionaltechniques for the preparation/isolation of individual enantiomersinclude synthesis from a suitable optically pure precursor, asymmetricsynthesis from achiral starting materials, or resolution of anenantiomeric mixture, for example, chiral chromatography,recrystallization, resolution, diastereomeric salt formation, orderivatization into diastereomeric adducts followed by separation.

When the compound provided herein contains an acidic or basic moiety, itmay also be provided as a pharmaceutically acceptable salt. See, Bergeet al., J. Pharm.

Methods of Synthesis

The compounds provided herein can be prepared, isolated, or obtained byany method known to one of skill in the art. For an example, a compoundof Formula I can be prepared as shown in Scheme I.

Compound I-1 is treated with nucleophilic amine I-2 to form compoundI-3, wherein X¹ is a leaving group, including, but not limited tofluoro, chloro, bromo, methoxy, ethoxy, and nitro. The nitro group ofcompound 1-3 is reduced with a reducing agent, e.g., zinc, FeCl₂, NiCl₂,or Na₂S₂O₃, to form compound 1-4. The reduction can also be accomplishedvia hydrogenation using, e.g., ammonium formate or hydrogen in thepresence of Pd/C. Compound I-5 is then cyclized to form compound I-5with the Z group installed simultaneously. When Z is NH, compound I-5 isthen coupled with an acid (R²COOH) using a coupling reagent, e.g., HATU,HBTU, PyBroP, PyBOP, or EDCI, to form compound of Formula I.

In certain embodiments, the pharmaceutical compositions provided hereinin a modified release dosage form is formulated using an erodible matrixdevice, which is water-swellable, erodible, or soluble polymers,including, but not limited to, synthetic polymers, and naturallyoccurring polymers and derivatives, such as polysaccharides andproteins.

Materials useful in forming an erodible matrix include, but are notlimited to, chitin, chitosan, dextran, and pullulan; gum agar, gumarabic, gum karaya, locust bean gum, gum tragacanth, carrageenans, gumghatti, guar gum, xanthan gum, and scleroglucan; starches, such asdextrin and maltodextrin; hydrophilic colloids, such as pectin;phosphatides, such as lecithin; alginates; propylene glycol alginate;gelatin; collagen; cellulosics, such as ethyl cellulose (EC),methylethyl cellulose (MEC), carboxymethyl cellulose (CMC), CMEC,hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), celluloseacetate (CA), cellulose propionate (CP), cellulose butyrate (CB),cellulose acetate butyrate (CAB), CAP, CAT, hydroxypropyl methylcellulose (HPMC), HPMCP, HPMCAS, hydroxypropyl methyl cellulose acetatetrimellitate (HPMCAT), and ethyl hydroxyethyl cellulose (EHEC);polyvinyl pyrrolidone; polyvinyl alcohol; polyvinyl acetate; glycerolfatty acid esters; polyacrylamide; polyacrylic acid; copolymers ofethacrylic acid or methacrylic acid (EUDRAGIT®, Rohm America, Inc.,Piscataway, N.J.); poly(2-hydroxyethyl-methacrylate); polylactides;copolymers of L-glutamic acid and ethyl-L-glutamate; degradable lacticacid-glycolic acid copolymers; poly-D-(−)-3-hydroxybutyric acid; andother acrylic acid derivatives, such as homopolymers and copolymers ofbutylmethacrylate, methyl methacrylate, ethyl methacrylate,ethylacrylate, (2-dimethylaminoethyl)methacrylate, and(trimethylaminoethyl)methacrylate chloride.

The pharmaceutical compositions provided herein in a modified releasedosage form can be prepared by methods known to those skilled in theart, including direct compression, dry or wet granulation followed bycompression, and melt-granulation followed by compression.

2. Osmotic Controlled Release Devices

The pharmaceutical compositions provided herein in a modified releasedosage form can be fabricated using an osmotic controlled releasedevice, including, but not limited to, one-chamber system, two-chambersystem, asymmetric membrane technology (AMT), and extruding core system(ECS). In general, such devices have at least two components: (a) a corewhich contains an active ingredient; and (b) a semipermeable membranewith at least one delivery port, which encapsulates the core. Thesemipermeable membrane controls the influx of water to the core from anaqueous environment of use so as to cause drug release by extrusionthrough the delivery port(s).

In addition to the active ingredient(s), the core of the osmotic deviceoptionally includes an osmotic agent, which creates a driving force fortransport of water from the environment of use into the core of thedevice. One class of osmotic agents is water-swellable hydrophilicpolymers, which are also referred to as “osmopolymers” and “hydrogels.”Suitable water-swellable hydrophilic polymers as osmotic agents include,but are not limited to, hydrophilic vinyl and acrylic polymers,polysaccharides such as calcium alginate, polyethylene oxide (PEO),polyethylene glycol (PEG), polypropylene glycol (PPG),poly(2-hydroxyethyl methacrylate), poly(acrylic) acid, poly(methacrylic)acid, polyvinylpyrrolidone (PVP), crosslinked PVP, polyvinyl alcohol(PVA), PVA/PVP copolymers, PVA/PVP copolymers with hydrophobic monomerssuch as methyl methacrylate and vinyl acetate, hydrophilic polyurethanescontaining large PEO blocks, sodium croscarmellose, carrageenan,hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC),hydroxypropyl methyl cellulose (HPMC), carboxymethyl cellulose (CMC) andcarboxyethyl, cellulose (CEC), sodium alginate, polycarbophil, gelatin,xanthan gum, and sodium starch glycolate.

The other class of osmotic agents is osmogens, which are capable ofimbibing water to affect an osmotic pressure gradient across the barrierof the surrounding coating. Suitable osmogens include, but are notlimited to, inorganic salts, such as magnesium sulfate, magnesiumchloride, calcium chloride, sodium chloride, lithium chloride, potassiumsulfate, potassium phosphates, sodium carbonate, sodium sulfite, lithiumsulfate, potassium chloride, and sodium sulfate; sugars, such asdextrose, fructose, glucose, inositol, lactose, maltose, mannitol,raffinose, sorbitol, sucrose, trehalose, and xylitol; organic acids,such as ascorbic acid, benzoic acid, fumaric acid, citric acid, maleicacid, sebacic acid, sorbic acid, adipic acid, edetic acid, glutamicacid, p-toluenesulfonic acid, succinic acid, and tartaric acid; urea;and mixtures thereof.

Osmotic agents of different dissolution rates can be employed toinfluence how rapidly the active ingredient(s) is initially deliveredfrom the dosage form. For example, amorphous sugars, such as MANNOGEM™EZ (SPI Pharma, Lewes, Del.) can be used to provide faster deliveryduring the first couple of hours to promptly produce the desiredtherapeutic effect, and gradually and continually release of theremaining amount to maintain the desired level of therapeutic orprophylactic effect over an extended period of time. In this case, theactive ingredient(s) is released at such a rate to replace the amount ofthe active ingredient metabolized and excreted.

The core can also include a wide variety of other excipients andcarriers as described herein to enhance the performance of the dosageform or to promote stability or processing.

Materials useful in forming the semipermeable membrane include variousgrades of acrylics, vinyls, ethers, polyamides, polyesters, andcellulosic derivatives that are water-permeable and water-insoluble atphysiologically relevant pHs, or are susceptible to being renderedwater-insoluble by chemical alteration, such as crosslinking. Examplesof suitable polymers useful in forming the coating, include plasticized,unplasticized, and reinforced cellulose acetate (CA), cellulosediacetate, cellulose triacetate, CA propionate, cellulose nitrate,cellulose acetate butyrate (CAB), CA ethyl carbamate, CAP, CA methylcarbamate, CA succinate, cellulose acetate trimellitate (CAT), CAdimethylaminoacetate, CA ethyl carbonate, CA chloroacetate, CA ethyloxalate, CA methyl sulfonate, CA butyl sulfonate, CA p-toluenesulfonate, agar acetate, amylose triacetate, beta glucan acetate, betaglucan triacetate, acetaldehyde dimethyl acetate, triacetate of locustbean gum, hydroxylated ethylene-vinylacetate, EC, PEG, PPG, PEG/PPGcopolymers, PVP, HEC, HPC, CMC, CMEC, HPMC, HPMCP, HPMCAS, HPMCAT,poly(acrylic) acids and esters and poly-(methacrylic) acids and estersand copolymers thereof, starch, dextran, dextrin, chitosan, collagen,gelatin, polyalkenes, polyethers, polysulfones, polyethersulfones,polystyrenes, polyvinyl halides, polyvinyl esters and ethers, naturalwaxes, and synthetic waxes.

Semipermeable membrane can also be a hydrophobic microporous membrane,wherein the pores are substantially filled with a gas and are not wettedby the aqueous medium but are permeable to water vapor, as disclosed inU.S. Pat. No. 5,798,119. Such hydrophobic but water-vapor permeablemembrane are typically composed of hydrophobic polymers such aspolyalkenes, polyethylene, polypropylene, polytetrafluoroethylene,polyacrylic acid derivatives, polyethers, polysulfones,polyethersulfones, polystyrenes, polyvinyl halides, polyvinylidenefluoride, polyvinyl esters and ethers, natural waxes, and syntheticwaxes.

The delivery port(s) on the semipermeable membrane can be formedpost-coating by mechanical or laser drilling. Delivery port(s) can alsobe formed in situ by erosion of a plug of water-soluble material or byrupture of a thinner portion of the membrane over an indentation in thecore. In addition, delivery ports can be formed during coating process,as in the case of asymmetric membrane coatings of the type disclosed inU.S. Pat. Nos. 5,612,059 and 5,698,220.

The total amount of the active ingredient(s) released and the releaserate can substantially by modulated via the thickness and porosity ofthe semipermeable membrane, the composition of the core, and the number,size, and position of the delivery ports.

The pharmaceutical compositions in an osmotic controlled-release dosageform can further comprise additional conventional excipients or carriersas described herein to promote performance or processing of theformulation.

Example 1A Cell Proliferation Assay

The biological activity of a test compound was determined using cellproliferation assays. The activity against wild-type ERBB1 wasdetermined using A431 human epidermoid carcinoma cells (ATCC) and humanepidermal keratinocytes, neonatal, or HEKn cells (ATCC). The activityagainst mutant ERBB1 was determined using HCC827 human NSCLCadenocarcinoma cells (ATCC), which has a deletion of E746-A759 in exon19. The activity against a drug-resistant mutant ERBB1 was determinedusing H1975 human NSCLC adenocarcinoma cells (ATCC), which has the T790Mmutation in-cis with the L858R mutation.

A431 cells were grown in DMEM (Invitrogen) supplemented with 10% FBS(Lonza), 1% penicillin-streptomycin, and 2 mM glutamine (Invitrogen).HEKn cells were grown in EPILIFE® (Invitrogen) supplemented with HKGS(Invitrogen). HCC827 and H1975 were cultured in RPMI1640 supplementedwith 10% FBS (Lonza), 1% penicillin-streptomycin, and 2 mM glutamine(Invitrogen). Cells were maintained and propagated at 37° C. and 5% CO2in a humidified cell culture incubator. Aliquots of cells from earlypassages were preserved for liquid nitrogen storage. Frozen vials ofcells were thawed at 37° C. water bath. Cells were spun to removefreezing medium. The newly revived frozen cells were adapted in culturefor 10 days before used for compound testing. Cells used in the assaywere less than 20 subculture passages or 3 months in culture.

The test compounds were dissolved in dimethylsulfoxide (DMSO) and storedat −20° C. before testing. For the cell proliferation assays, cells wereseeded in 96-well plates (Costar, 3917) at various numbers: A431 cellsat 2,000 cells per well, HEKn, HCC827, and H1975 at 1,000 cells perwell. The cells were placed in a culture incubator overnight. Next day,test compounds in DMSO were added to the cells and placed back in theculture incubator for 72 hrs. In the meantime, the cell numbers at timezero of the compound treatment (T0) was measured by ENERCOUNT® (CodexBioSolutions). At the end of the compound treatment, the cell numberswere again measured by EnerCount as T72 values. The untreated controls(Ctrl) were cell numbers recorded from the 0.1% DMSO treatment. Thepercent growth inhibition by the test compound was calculated by theformula: (1-(T72-T0)/(Ctrl-T0))×100. The GI₅₀, the compoundconcentration at which 50% of cell growth is inhibited, was determinedfrom the 10-point dose-response growth inhibition using non-linearsigmoidal curve fitting using GraphPad Prism.

The results are summarized in Tables 1 and 2, wherein A represents avalue no greater than 500 nM, B represents a value greater than 500 nMbut no greater than 1 μM, C represents a value greater than 1 μM but nogreater than 5 and D represents a value greater than 5μM; and wherein A′represents a ratio of greater than 10, B′ represents a ratio of nogreater than 10 but no less than 5, C′ represents a ratio of no greaterthan 5 but no less than 2, and D′ represents a ratio of no greater than2.

In the primary reaction, the kinase transfers the gamma-phosphate of ATPto a single tyrosine, serine, or threonine residue in the syntheticFRET-peptide substrate. In the secondary reaction, a site-specificprotease recognizes and cleaves non-phosphorylated FRET-peptides.Cleavage disrupts FRET between the donor and acceptor fluorophores onthe FRET-peptide, whereas uncleaved, phosphorylated FRET-peptidesmaintain FRET. An inhibitory activity of a compound is thus determinedfrom its effect on the cleavage of the synthetic FRET-peptide substrate.

Inhibition of BMX, BTK, ITK, and TXK kinases by a test compound isdetermined in 50 mM HEPES, pH 7.5, 0.01% BRIJ-35, 10 mM MgCl₂, and 1 mMEGTA in the presence of 1% DMSO by volume.

Example 3A LANTHASCREEN® Eu Kinase Assay

Binding of an ALEXA FLUOR® conjugate or “tracer” to a kinase is detectedby addition of a Eu-labeled anti-tag antibody. Binding of the tracer andantibody to a kinase results in a high degree of FRET, whereasdisplacement of the tracer with a kinase inhibitor results in a loss ofFRET. An inhibitory activity of a compound is thus determined from theextent of the FRET signal loss. Inhibition of ITK and TEC kinases by atest compound is determined in the presence of 1% DMSO.
